Hello everyone,

I've recently bought a new PC but have kept my old HIS Radeon 6970 as the grafic card. Now I've bought a used Sapphire Radeon 6970 (880 Mhz as well) and tried to join them via crossfire (the one in the grey and the other one in the first black PCIe slot). The  problem is that the PC freezes after 2-3 minutes of working.

I've seen that people are having the same problem here but found no topic where this problem would have been really solved. Probably you could help me and the others who suffer under the same problem?

My specs (apart of the grafics):


- ASUS Z170 Pro Gaming motherboard

- Intel Core i5 6600k

- 2x8 Gb G.skill rip Jaws DDR4-3200


I'm sure that the problem is with the crossfire because everything is working pretty good with one graphic card. I've also tried changing some settings in BIOS but without any result.


Thanks a lot in advance!
